Part I.

Foundation Of Constantinople. -- Political System Constantine, And His Successors. -- Military Discipline. -- The Palace. -- The Finances.

The unfortunate Licinius was the last rival who opposed the greatness, and the last captive who adorned the triumph, of Constantine. After a tranquil and prosperous reign, the conqueror bequeathed to his family the inheritance of the Roman empire; a new capital, a new policy, and a new religion; and the innovations which he established have been embraced and consecrated by succeeding generations. The age of the great Constantine and his sons is filled with important events; but the historian must be oppressed by their number and variety, unless he diligently separates from each other the scenes which are connected only by the order of time. He will describe the political institutions that gave strength and stability to the empire, before he proceeds to relate the wars and revolutions which hastened its decline. He will adopt the division unknown to the ancients of civil and ecclesiastical affairs: the victory of the Christians, and their intestine discord, will supply copious and distinct materials both for edification and for scandal.

After the defeat and abdication of Licinius, his victorious rival proceeded to lay the foundations of a city destined to reign in future times, the mistress of the East, and to survive the empire and religion of Constantine. The motives, whether of pride or of policy, which first induced Diocletian to withdraw himself from the ancient seat of government, had acquired additional weight by the example of his successors, and the habits of forty years. Rome was insensibly confounded with the dependent kingdoms which had once acknowledged her supremacy; and the country of the Cæsars was viewed with cold indifference by a martial prince, born in the neighborhood of the Danube, educated in the courts and armies of Asia, and invested with the purple by the legions of Britain. The Italians, who had received Constantine as their deliverer, submissively obeyed the edicts which he sometimes condescended to address to the senate and people of Rome; but they were seldom honored with the presence of their new sovereign. During the vigor of his age, Constantine, according to the various exigencies of peace and war, moved with slow dignity, or with active diligence, along the frontiers of his extensive dominions; and was always prepared to take the field either against a foreign or a domestic enemy. But as he gradually reached the summit of prosperity and the decline of life, he began to meditate the design of fixing in a more permanent station the strength as well as majesty of the throne. In the choice of an advantageous situation, he preferred the confines of Europe and Asia; to curb with a powerful arm the barbarians who dwelt between the Danube and the Tanais; to watch with an eye of jealousy the conduct of the Persian monarch, who indignantly supported the yoke of an ignominious treaty. With these views, Diocletian had selected and embellished the residence of Nicomedia: but the memory of Diocletian was justly abhorred by the protector of the church: and Constantine was not insensible to the ambition of founding a city which might perpetuate the glory of his own name. During the late operations of the war against Licinius, he had sufficient opportunity to contemplate, both as a soldier and as a statesman, the incomparable position of Byzantium; and to observe how strongly it was guarded by nature against a hostile attack, whilst it was accessible on every side to the benefits of commercial intercourse. Many ages before Constantine, one of the most judicious historians of antiquity had described the advantages of a situation, from whence a feeble colony of Greeks derived the command of the sea, and the honors of a flourishing and independent republic.

If we survey Byzantium in the extent which it acquired with the august name of Constantinople, the figure of the Imperial city may be represented under that of an unequal triangle. The obtuse point, which advances towards the east and the shores of Asia, meets and repels the waves of the Thracian Bosphorus. The northern side of the city is bounded by the harbor; and the southern is washed by the Propontis, or Sea of Marmara. The basis of the triangle is opposed to the west, and terminates the continent of Europe. But the admirable form and division of the circumjacent land and water cannot, without a more ample explanation, be clearly or sufficiently understood.

The winding channel through which the waters of the Euxine flow with a rapid and incessant course towards the Mediterranean, received the appellation of Bosphorus, a name not less celebrated in the history, than in the fables, of antiquity. A crowd of temples and of votive altars, profusely scattered along its steep and woody banks, attested the unskilfulness, the terrors, and the devotion of the Grecian navigators, who, after the example of the Argonauts, explored the dangers of the inhospitable Euxine. On these banks tradition long preserved the memory of the palace of Phineus, infested by the obscene harpies; and of the sylvan reign of Amycus, who defied the son of Leda to the combat of the cestus. The straits of the Bosphorus are terminated by the Cyanean rocks, which, according to the description of the poets, had once floated on the face of the waters; and were destined by the gods to protect the entrance of the Euxine against the eye of profane curiosity. From the Cyanean rocks to the point and harbor of Byzantium, the winding length of the Bosphorus extends about sixteen miles, and its most ordinary breadth may be computed at about one mile and a half. The new castles of Europe and Asia are constructed, on either continent, upon the foundations of two celebrated temples, of Serapis and of Jupiter Urius. The oldcastles, a work of the Greek emperors, command the narrowest part of the channel in a place where the opposite banks advance within five hundred paces of each other. These fortresses were destroyed and strengthened by Mahomet the Second, when he meditated the siege of Constantinople: but the Turkish conqueror was most probably ignorant, that near two thousand years before his reign, continents by a bridge of boats. At a small distance from the old castles we discover the little town of Chrysopolis, or Scutari, which may almost be considered as the Asiatic suburb of Constantinople. The Bosphorus, as it begins to open into the Propontis, passes between Byzantium and Chalcedon. The latter of those cities was built by the Greeks, a few years before the former; and the blindness of its founders, who overlooked the superior advantages of the opposite coast, has been stigmatized by a proverbial expression of contempt.

The harbor of Constantinople, which may be considered as an arm of the Bosphorus, obtained, in a very remote period, the denomination of the Golden Horn. The curve which it describes might be compared to the horn of a stag, or as it should seem, with more propriety, to that of an ox. The epithet of golden was expressive of the riches which every wind wafted from the most distant countries into the secure and capacious port of Constantinople. The River Lycus, formed by the conflux of two little streams, pours into the harbor a perpetual supply of fresh water, which serves to cleanse the bottom, and to invite the periodical shoals of fish to seek their retreat in that convenient recess. As the vicissitudes of tides are scarcely felt in those seas, the constant depth of the harbor allows goods to be landed on the quays without the assistance of boats; and it has been observed, that in many places the largest vessels may rest their prows against the houses, while their sterns are floating in the water. From the mouth of the Lycus to that of the harbor, this arm of the Bosphorus is more than seven miles in length. The entrance is about five hundred yards broad, and a strong chain could be occasionally drawn across it, to guard the port and city from the attack of a hostile navy.

Between the Bosphorus and the Hellespont, the shores of Europe and Asia, receding on either side, enclose the sea of Marmara, which was known to the ancients by the denomination of Propontis. The navigation from the issue of the Bosphorus to the entrance of the Hellespont is about one hundred and twenty miles. Those who steer their westward course through the middle of the Propontis, amt at once descry the high lands of Thrace and Bithynia, and never lose sight of the lofty summit of Mount Olympus, covered with eternal snows. They leave on the left a deep gulf, at the bottom of which Nicomedia was seated, the Imperial residence of Diocletian; and they pass the small islands of Cyzicus and Proconnesus before they cast anchor at Gallipoli; where the sea, which separates Asia from Europe, is again contracted into a narrow channel.

The geographers who, with the most skilful accuracy, have surveyed the form and extent of the Hellespont, assign about sixty miles for the winding course, and about three miles for the ordinary breadth of those celebrated straits. But the narrowest part of the channel is found to the northward of the old Turkish castles between the cities of Sestus and Abydus. It was here that the adventurous Leander braved the passage of the flood for the possession of his mistress. It was here likewise, in a place where the distance between the opposite banks cannot exceed five hundred paces, that Xerxes imposed a stupendous bridge of boats, for the purpose of transporting into Europe a hundred and seventy myriads of barbarians. A sea contracted within such narrow limits may seem but ill to deserve the singular epithet of broad, which Homer, as well as Orpheus, has frequently bestowed on the Hellespont. * But our ideas of greatness are of a relative nature: the traveller, and especially the poet, who sailed along the Hellespont, who pursued the windings of the stream, and contemplated the rural scenery, which appeared on every side to terminate the prospect, insensibly lost the remembrance of the sea; and his fancy painted those celebrated straits, with all the attributes of a mighty river flowing with a swift current, in the midst of a woody and inland country, and at length, through a wide mouth, discharging itself into the Ægean or Archipelago. Ancient Troy, seated on a an eminence at the foot of Mount Ida, overlooked the mouth of the Hellespont, which scarcely received an accession of waters from the tribute of those immortal rivulets the Simois and Scamander. The Grecian camp had stretched twelve miles along the shore from the Sigæan to the Rhætean promontory; and the flanks of the army were guarded by the bravest chiefs who fought under the banners of Agamemnon. The first of those promontories was occupied by Achilles with his invincible myrmidons, and the dauntless Ajax pitched his tents on the other. After Ajax had fallen a sacrifice to his disappointed pride, and to the ingratitude of the Greeks, his sepulchre was erected on the ground where he had defended the navy against the rage of Jove and of Hector; and the citizens of the rising town of Rhæteum celebrated his memory with divine honors. Before Constantine gave a just preference to the situation of Byzantium, he had conceived the design of erecting the seat of empire on this celebrated spot, from whence the Romans derived their fabulous origin. The extensive plain which lies below ancient Troy, towards the Rhætean promontory and the tomb of Ajax, was first chosen for his new capital; and though the undertaking was soon relinquished the stately remains of unfinished walls and towers attracted the notice of all who sailed through the straits of the Hellespont.

We are at present qualified to view the advantageous position of Constantinople; which appears to have been formed by nature for the centre and capital of a great monarchy. Situated in the forty-first degree of latitude, the Imperial city commanded, from her seven hills, the opposite shores of Europe and Asia; the climate was healthy and temperate, the soil fertile, the harbor secure and capacious; and the approach on the side of the continent was of small extent and easy defence. The Bosphorus and the Hellespont may be considered as the two gates of Constantinople; and the prince who possessed those important passages could always shut them against a naval enemy, and open them to the fleets of commerce. The preservation of the eastern provinces may, in some degree, be ascribed to the policy of Constantine, as the barbarians of the Euxine, who in the preceding age had poured their armaments into the heart of the Mediterranean, soon desisted from the exercise of piracy, and despaired of forcing this insurmountable barrier. When the gates of the Hellespont and Bosphorus were shut, the capital still enjoyed within their spacious enclosure every production which could supply the wants, or gratify the luxury, of its numerous inhabitants. The sea-coasts of Thrace and Bithynia, which languish under the weight of Turkish oppression, still exhibit a rich prospect of vineyards, of gardens, and of plentiful harvests; and the Propontis has ever been renowned for an inexhaustible store of the most exquisite fish, that are taken in their stated seasons, without skill, and almost without labor. But when the passages of the straits were thrown open for trade, they alternately admitted the natural and artificial riches of the north and south, of the Euxine, and of the Mediterranean. Whatever rude commodities were collected in the forests of Germany and Scythia, and far as the sources of the Tanais and the Borysthenes; whatsoever was manufactured by the skill of Europe or Asia; the corn of Egypt, and the gems and spices of the farthest India, were brought by the varying winds into the port of Constantinople, which for many ages attracted the commerce of the ancient world.

The prospect of beauty, of safety, and of wealth, united in a single spot, was sufficient to justify the choice of Constantine. But as some decent mixture of prodigy and fable has, in every age, been supposed to reflect a becoming majesty on the origin of great cities, the emperor was desirous of ascribing his resolution, not so much to the uncertain counsels of human policy, as to the infallible and eternal decrees of divine wisdom. In one of his laws he has been careful to instruct posterity, that in obedience to the commands of God, he laid the everlasting foundations of Constantinople: and though he has not condescended to relate in what manner the celestial inspiration was communicated to his mind, the defect of his modest silence has been liberally supplied by the ingenuity of succeeding writers; who describe the nocturnal vision which appeared to the fancy of Constantine, as he slept within the walls of Byzantium. The tutelar genius of the city, a venerable matron sinking under the weight of years and infirmities, was suddenly transformed into a blooming maid, whom his own hands adorned with all the symbols of Imperial greatness. The monarch awoke, interpreted the auspicious omen, and obeyed, without hesitation, the will of Heaven The day which gave birth to a city or colony was celebrated by the Romans with such ceremonies as had been ordained by a generous superstition; and though Constantine might omit some rites which savored too strongly of their Pagan origin, yet he was anxious to leave a deep impression of hope and respect on the minds of the spectators. On foot, with a lance in his hand, the emperor himself led the solemn procession; and directed the line, which was traced as the boundary of the destined capital: till the growing circumference was observed with astonishment by the assistants, who, at length, ventured to observe, that he had already exceeded the most ample measure of a great city. "I shall still advance," replied Constantine, "till He, the invisible guide who marches before me, thinks proper to stop." Without presuming to investigate the nature or motives of this extraordinary conductor, we shall content ourselves with the more humble task of describing the extent and limits of Constantinople.

In the actual state of the city, the palace and gardens of the Seraglio occupy the eastern promontory, the first of the seven hills, and cover about one hundred and fifty acres of our own measure. The seat of Turkish jealousy and despotism is erected on the foundations of a Grecian republic; but it may be supposed that the Byzantines were tempted by the conveniency of the harbor to extend their habitations on that side beyond the modern limits of the Seraglio. The new walls of Constantine stretched from the port to the Propontis across the enlarged breadth of the triangle, at the distance of fifteen stadia from the ancient fortification; and with the city of Byzantium they enclosed five of the seven hills, which, to the eyes of those who approach Constantinople, appear to rise above each other in beautiful order. About a century after the death of the founder, the new buildings, extending on one side up the harbor, and on the other along the Propontis, already covered the narrow ridge of the sixth, and the broad summit of the seventh hill. The necessity of protecting those suburbs from the incessant inroads of the barbarians engaged the younger Theodosius to surround his capital with an adequate and permanent enclosure of walls. From the eastern promontory to the golden gate, the extreme length of Constantinople was about three Roman miles; the circumference measured between ten and eleven; and the surface might be computed as equal to about two thousand English acres. It is impossible to justify the vain and credulous exaggerations of modern travellers, who have sometimes stretched the limits of Constantinople over the adjacent villages of the European, and even of the Asiatic coast. But the suburbs of Pera and Galata, though situate beyond the harbor, may deserve to be considered as a part of the city; and this addition may perhaps authorize the measure of a Byzantine historian, who assigns sixteen Greek (about fourteen Roman) miles for the circumference of his native city. Such an extent may not seem unworthy of an Imperial residence. Yet Constantinople must yield to Babylon and Thebes, to ancient Rome, to London, and even to Paris.
